The damage to the right side was based off the Mech's optics in the reference picture. I believed slamming a large block of basalt (I believe you said as big as someone's head) down on top of the Optics shown would damage the protruding lens because it's higher up and has less protection. That was my effort at conciliation, because I personally doubted the lens could be damaged at all by blunt force from above, but I could just about justify that damage logically.
